It appears as  
rev-server=192.168.1.0/24,192.168.1.1  
server=//192.168.1.1  
server=/some.lan/192.168.1.1

when it only needs to be .....

rev-server=192.168.1.0/24,192.168.1.1  
server=/some.lan/192.168.1.1

What file is this? What is the output of the following from the Pi terminal?

`sudo grep -v '#\|^$' -R /etc/dnsmasq.*`

Do you have `Never Forward non-FQDNs` checked or unchecked in Settings?

Yes, that tells FTL to forward unqualified names (hostnames without domains) to the rev-server for conditional forwarding.

I don't know why, but now I am experiencing issues resolving IPV6 names with this added. And I just updated yesterday, so this issue is new. Now all my ipv6 lookups are coming as refused. Before this addition they were accepted.

@SomeWhereOutThere I don't think this will be related to the recent change.

- Can you try re-checking the box?
- Why did you un-check it in the first place (there are good reasons to do this but what caused you doing it)?
- Does the issue you observe vanish when you remove the line manually and run

```auto
pihole restartdns

```

?

The Box is unchecked because I am not using Pihole for DHCP. I am using it only for DNS and conditional forwarding. I was under the impression this option should only be checked if the pihole user was issue DHCP via Pihole as oppose to via a Router DHCP assignment.
